For my readers who are preparing the ocm 11g exam, the environment just changed (From 13th May 2013 onwards)
Instead of using OEM 10g, you will be using OEM 11g.
The upgrade exam is still using OEM 10g and DB 11gR1 (!) but I did not care installing OEM 10g and I prepared with OEM 11g.
Thanks for notification ! Do you think it’s an issue to even use Cloud Control 12c, I clearly do not want to move backward on this…
you can do most tasks in command line anyway. It was a very long time I last deployed 10g oem and I was pretty lucky and not well prepared on the 10g installation. But it is just a web tool and you are doing database OCM not middleware OCM
